DN15mm-DN40mm Small Pipe Size Low Flow Rate Ultrasonic Liquid Flow Meter
I. Features

II. Advantages of Ultrasonic Flowmeters
- No moving parts: Traditional mechanical flowmeters measure pressure through the use of moving parts, which serve as mechanical sensors. Unfortunately, these parts pose several problems. They often obstruct flow and cause pressure loss. The moving parts also degrade over time, providing less accurate results and requiring repair and replacement. Since there are no moving parts in ultrasonic flowmeters, you don’t have to worry about them degrading or creating a blockage.
- Low maintenance: Since ultrasonic flowmeters don’t involve moving parts, they last a long time with very little maintenance. They also have low power consumption, so they often last for several years before the batteries need to be replaced.
- Digital and analog options: Ultrasonic flowmeters come in a wide range of outputs, and advanced technology has allowed for the creation of ultrasonic transducers with digital readouts and network connection capabilities. This means that transducers can communicate measurements in real time to a central monitoring system.
- High accuracy: As long as the meter is properly mounted and installed, these meters are highly accurate. However, inline and insertion flowmeters are generally more accurate than clamp-on ultrasonic flowmeters.
